WILLIAM GALLAHER, OF ST. LOUIS, MISSOURI.

HEATER FOR AUTOMOBILE-RADIATORS.

To all whom 2'25 may concern Be it known that I, WILLIAM GALLAHER, a citizen of the United States, residing at city of St. Louis, State of Missouri, have invented a certain new and useful Improvement in Heaters for Automobile-Radiators, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appert-ains to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which Figure 1 is a front elevational view of an ordinary form of automobile radiator showing my improved heater in position there in. Fig. 2 is a vertical sectional View on line 22 of Fig. 1. Fig. 3 is an enlarged detail view showing the socket plug attached.

This invention relates to a new and useful improvement in heaters for automobile radiators, the object being to construct a device of the character described which is simple, cheap and effective, one which is quickly applied and one which is quickly placed into service and disconnected when not in use.

In cold weather, great trouble is experienced at times by owners of automobiles because of the water freezing inthe radiator and to avoid this it is necessary to build a fire in the garage so as to have a temperature sufiiciently high to avoid the freezing difficulty.

My present invention consists in acasing inserted in the lower portion of the water containing chamber of the radiator in which casing is arranged one or more electrical heating units, the outer end of the casing being closed by an insulation socket with which cooperates an ordinary insulated plug connected by wires to the usual lamp socket of an electric circuit. While I have shown the heating medium as consisting of an electric heating unit or units, it is obvious that gas or steam could be employed as a heating Specification of Letters Patent.

medium, but this of course would not be as convenient or accessible at times though it would as successfully serve the purpose.

In the drawings, 1 indicates the radiator of an automobile of usual construction. Preferably in the lower portion of this radiator is arranged a casing or housing, preferably cup shaped in form, and having its outwardly disposed flanges secured to the front wall of the radiator by means of rivets or other suitable securing devices, the joint being made water tight for obvious reasons.

3 indicates an insulation plug having suitable links t therein in which are located terminals 5 of the wires which lead to the heating coil or coils 6.

7 indicates a plug preferably made of insulation material and having the terminal pins 8 to which the wires 9 from an electric circuit are connected. These wires 9 may lead from a plug arranged in an ordinary lamp socket.

In operation, if it is desired to use the heater, the plug is inserted in position so that the current flowing through the heating coils will generate suhicient heat to cause a circulation of tlie water in the radiator and thereby prevent its freezing.

lVhat I claim is:

In an automobile, a radiator having a fluid containing compartment, a heat generating element disposed in the lower portion of said fluid containing compartment and signature in the presence of two witnesses,
